Abstract: 1,209,923. Electro-photographic apparatus. RICOH CO. Ltd. Oct.17, 1967 [Oct.18, 1966; Nov.10, 1966], No.47240/67. Heading G2H. An electro-photographic colour apparatus has means for moving a photo-conductive sheet sequentially through charging, exposure, and development stations in a recurring path so as to expose the sheet to a first colour to form a latent image which is developed with a pigment of that colour and similarly for a second and, if desired, a third colour. As shown, a conveyer 1 carries a photo-conductor sheet and sequentially and repeatedly between a corona device having electrodes 6, 7 to charge the sheet uniformly before exposure at station 10 having a projector 11 fitted with turret mounted filters 13, 14, 15 corresponding to the primary colours which can be selectively brought to operative position. Development of latent images so produced is effected by developer baths 17, 18, and 19, the bath 19 containing developer corresponding to the filter 13, the bath 18 developer corresponding to the filter 14, and the bath 19 developer corresponding to the filter 15. The developer comprises a pigment of the selected colour in a volatile insulating carrier liquid including a fixing medium effective when the liquid is evaporated. The developer baths each comprise a reservoir 20, Fig. 2 having inclined vanes 21 actuated by a crank to cause developer to be splashed upwardly to the face of the sheet to be developed. In another embodiment, of developer bath Fig.3 (not shown) a flap valve (31) having a flexible membrane (33) is oscillated by a shaft (34) of an oscillating motor (35) to direct developer upwardly through fixed vanes (36).

Abstract: 993,578. Television; cathode - ray tube mountings. FERNSEH G.m.b.H. Dec. 21, 1962 [Dec. 21, 1961], No. 48300/62. Headings H4F and H4T. A television camera comprises a pick-up tube 1 and a preamplifier (the constructional details of which are not illustrated) to which picture signals developed by the pick-up tube are applied, the preamplifier being carried by a mounting member 4 concentrically surrounding the neck of the pick-up tube and carrying at its centre a socket adapted to engage the base of the pick-up tube, the socket being arranged for axial movement but prevented from rotation (by means not illustrated) with respect to the mounting member. The socket is situated within a concentric shell guide 5 and is limited in one direction of axial movement by an annular stop 13 and in the other direction of movement by a circular clip 14 which is fitted to guide 5 after the insertion of socket 6. The pick-up tube is surrounded by a coil assembly 2 to which member 4 is attached by pillars. The front of the coil assembly is closed by a removable plate (not illustrated) having an opening to admit light to the photo-cathode of the pick-up tube and against which the pick-up tube must be held in order to ensure that the photo-cathode is placed in the prescribed position in relation to the optical system of the camera. For this purpose the base of the pick-up tube is engaged by a ring 9 which urges the tube towards the front of the coil assembly under the influence of tension spring 10 secured to the rear of the coil assembly. The axial freedom of socket 6 in guide 5 allows the necessary movement. Ring 9 carries a cylindrical member 10 which is guided for movement by cylindrical member 16 attached to the coil assembly 2. The construction according to the invention, which is said to be particularly applicable to imageorthicon cameras, provides a compact and unitary tube and preamplifier assembly in which the lead from the tube to amplifier may be made short and of low capacitance since the amplifier accompanies the tube during axial movement for focus adjustment.

The term titanide designates any solid solution or alloy or intermetallic compound of Ti and the base metal. The cell generates electric current. The deposition rate of the Ti may be increased by impressing a voltage, e.g. to obtain constant current densities during the reaction. Specified fluorides, that may be used are those of Li, Na, K, Rb and Cs. e.g. a eutectic mixture of (i) NaF and LiF, (ii) LiF, NaF and KF or (iii) LiF and KF. An inert atmosphere of Ar, He, Ne, Kr, or Xe may be used. Impurities such as oxygen and carbon can be removed from the fused electrolyte by an initial electrolysis. Oxygen can also be removed by contacting the fused electrolyte with Ti. Carbon can also be removed by filtering the fused salt through a finely woven wire cloth especially of materials which will react with the carbon to make metal carbides. The titanide has a hard, wearresistant surface.
